Although above-mentioned patent can make electronic chip detection part, the contact with probe is abundant, and there is no be directed to draw
Foot length difference be easy to cause chip or pin to damage and makes improvement, and problem is not solved effectively still.
Utility model content
The utility model provides a kind of chip detection jig, for solving to detect jig in the prior art for different vendor
Or the electronic chip of specification, when easily occurring in detection compression, the pressing plate for detecting jig cannot be pressed against closure, and be easy to
Cause the technical issues of damage of chip and pin；Meanwhile the utility model also can solve electronic chip and be easy mistake on pedestal
The problem of position.
The technology employed by the present utility model is
A kind of chip detection jig is to solve existing detection jig for the electronic chip of different vendor or specification, holds
When easily appearing in detection compression, the pressing plate for detecting jig cannot be pressed against closure, and easily cause the damage of chip and pin
The problem of, including jig bottom plate and it is hinged on the flip lid pressing plate of jig bottom plate one end, the top surface of the jig bottom plate, which is equipped with, to be used
In the elastic supporting plate of chip placement, the surrounding of elastic supporting plate is provided with several and matched detection probe of chip pin, described to turn over
The corresponding elastic supporting plate in the bottom surface of lid pressing plate is provided with the spring bearer plate for compressing chip.
The operation principle and process of this detection jig:
Flip lid pressing plate is raised from jig bottom plate first, then downward by chip pin to be detected, is placed into elasticity
On supporting plate, so that the pin of chip is directed at detection probe, then downwardly turn over flip lid pressing plate, chip is compressed, is allowed to keep and examine
The state of probing needle relative securement, while the detection to chip is carried out, when compressing chip, because of the pin length of chip
Although can be because manufacturer is different and different, overall length difference when pin length is longer, not be turned over renovating pressing plate away from little
When turning closure, pin has just been contradicted in detection probe, and during renovating pressing plate closure, elastic supporting plate and elasticity
Pressing plate can automatic compression adjustment its thickness so that after flip lid pressing plate closure, pin will not be subject to large compressive and damage
Bad situation, is damaged in the detection process so as to avoid chip, is adapted to the core of different-thickness and different pin lengths
Piece is detected, and does not also need to be detected by the way of welding, easy to use and adaptable.
Further, in order to guarantee that elastic supporting plate can include upper branch according to its thickness of pressure automatic synchronization, elastic supporting plate
Plate and lower carrier plate pass through at least two groups of springs elastic connections between the upper supporting plate and lower carrier plate.By spring as upper branch
Hinge support between plate and lower carrier plate, during renovating pressing plate closure, upper supporting plate and lower carrier plate be subject to from chip
Pressure can groups of springs be compressed automatically, to adapt to the chip of different pin lengths, and chip can be clamped, be avoided
The case where chip misplaces, it is notable that groups of springs is preferably uniformly arranged between upper supporting plate and lower carrier plate, avoids branch
The case where plate and lower carrier plate tilt in compaction process.
Further, in order to guarantee that spring bearer plate can include upper pressure according to its thickness of pressure automatic synchronization, spring bearer plate
Plate and lower platen pass through three groups of springs elastic connections between the top board and lower platen.By spring as top board and
Hinge support between lower platen, during renovating pressing plate closure, the pressure from chip that top board and lower platen are subject to
Power can make groups of springs compress automatically, to adapt to the chip of different pin lengths, and can clamp chip, avoid chip
The case where dislocation, it is notable that groups of springs is preferably uniformly arranged between top board and lower platen, avoid top board and
The case where lower platen tilts in compaction process.
Further, each groups of springs being arranged on elastic supporting plate and spring bearer plate includes being uniformly arranged on the same line
Three springs, the coefficient of elasticity of the spring is identical, and the spring number that is arranged on elastic supporting plate, which is less than on spring bearer plate, to be arranged
Spring number.Herein it should be noted that being under pressure in identical situation in elastic supporting plate and spring bearer plate, preferential selection elasticity branch
Plate first compresses, and after pin is contacted with detection probe, by the support force of pin, then spring bearer plate deformation is compressed, therefore
The spring number being arranged on elastic supporting plate is less, it is possible to deformation first, and the spring number being arranged on spring bearer plate is more, so
Deformation afterwards.
Further, the top surface of jig bottom plate is removably connected with backing plate by bolt, and the centre of the backing plate, which is equipped with, opens
Mouthful, the elasticity supporting plate and detection probe are arranged in opening.The backing plate and opening of setting, can enable chip to exist
It after renovating pressing plate closure, is detected in the environment in an opposing seal, protects chip, and backing plate can be dismantled,
After depositing excessive dust in opening, the detection of chip can be impacted, so that the poor contact of pin and detection probe, and pad
After plate disassembly, it can be more convenient thoroughly to clear up dust.
Further, the thickness of elastic supporting plate and spring bearer plate and the depth less than opening.
Further, top board and upper supporting plate are contacted with the upper bottom surface of chip respectively, the surface of top board and upper supporting plate
It is equipped with several rubber antiskid salient points.The case where rubber antiskid salient point of setting can prevent in compaction process, and chip misplaces.
Further, the material of backing plate is any one in rubber or plastics.
The utility model has the following beneficial effects:
(1) for the utility model during renovating pressing plate closure, elastic supporting plate and spring bearer plate can automatic compression adjustments
Its thickness so that after flip lid pressing plate closure, pin will not be subject to large compressive and the case where damage, so as to avoid
Chip is damaged in the detection process, and the chip for being adapted to different-thickness and different pin lengths is detected, and is not also needed
It is detected by the way of welding, it is easy to use and adaptable.
(2) backing plate and opening of the utility model setting can enable chip after flip lid pressing plate closure, be in
It is detected in the environment of one opposing seal, protects chip, and backing plate can be dismantled, and deposit excessive dust in the opening
Afterwards, the detection of chip can be impacted, so that the poor contact of pin and detection probe, and after backing plate disassembly, it can be more square
Just the case where thoroughly cleaning dust, the rubber antiskid salient point of setting can prevent in compaction process, and chip misplaces.
